  • Fast connection
  • Guaranteed data transmission
  • Fast network configuration and modification
Connection Time  < 10 sec
Network Setup Time < 5 min (5-hop)
Remote Console Supported (Separate Time Slot ⇒ Payload not affected) Easy maintenance 
  • The transmission frame consists of 128 containers.
  • Each container is composed of one Control Box and eight Payload Boxes.
  • The Control Box is used for synchronization and control information transmission, while the Payload Box is used for data transmission.
  • Information is transmitted in units of symbols, each 16 bits in length.
  • Depending on the processing gain, each symbol may carry either 8 bits or 5 bits of information.
  • Adaptive Spanning Tree Network: Clone Master
    1. The Node relays the received registration request information to the higher-level Master.
    2. The Master allocates communication resources to the optimal Node.
    3. The Node that receives the resources becomes a Clone Master. 
    4. The Sensor transmits information through the nearest (or designated) Node.
